I've been running these drives for the past 2 years no issues there not the fastest but there very reliable

Instructions were easy to follow. It also comes with software to copy my older hard drive.

The HDD arrived well packaged and in great condition. I checked the drive before use and no errors were detected. Currently being used in a home NAS Server.

These are robust HDDs for NAS's. I already 2x of these which I bought almost 9 years ago, and running S.M.A.R.T tools on them yields around 50% life even after so many years of 24x7 usage as a NAS. The system I used it in was a Thecus Windows Storage Server, and two drives were configured in a mirror RAID configuration. A few years ago, Microsoft stopped support for WSS2012 so I migrated to Ubuntu server (using mdadm as a RAID mirror) and used that as a NAS. Around 2-3 years ago, I migrated that server's OS to FreeBSD (using zfs as the RAIDZ mirror) as it's been the most robust. This machine is still running with the 9'ish year old 4TB WD Reds. A few months ago (Holidays 2024), I bought another server class machine and built it using 3x of these new 4TB Reds. This machine is running RAIDZ1 zfs with Ubuntu, and has ~8TB capacity with one drive used for parity. One thing is for certain - RAIDZ almost doubles the read speed with these drives, and my bottleneck is the the 1Gbps LAN. I'm saturating the LAN with file transfers and I'm sure it would be faster if I change my cabling (currently CAT5e). Time will tell, and I'm hoping that these new 4TBs last as long as my almost 9 year old ones.

I have ordered nearly 100 of these drives over the last 5 years and they are always reliable and offer great performance in the NAS systems we put them in.

Purchased from Best Buy and using it in my NAS; the SanDisk 4TB HDD delivers consistent performance, runs quietly, and has proven to be reliable for continuous use.

Reliable storage for media collections not reliant on high access speed, Movie, Pictures, music, etc,

Working great so far. Was priced very competively for these types of drives

I bought two of these drives for a new NAS. They were simple and easy to install, and they are behaving just as expected.

Had this running in a Ugreen NAS for a while now and works great. Lots of storage and good transfer speeds. Looking to get a second one with more storage now.

Works well, win11 have to dig to get disk working, slide in for current drive.

An incredible little drive for a home NAS. Works as advertised on the box. Easy to install and configure.

Installed very easy. Format went without a hitch. I set two up as a Raid 1 array. Dumped my old HD 1 Tb on it and did a system repair and a OS clone for safe keeping. So far all working just fine.

Purchased this to replace a failing drive in a NAS set in a Raid array. Has been working flawlessly since I installed it. Most likely will purchase another to make them matching.

Excellent Hard Drive. Works like a charm and very reliable.

I have had good luck with these drive. They last well beyond their expected lifetime, really reliable and dependable. I am using 4 of these in a 4 drive redundant cluster and they hold up really well.

WD Red drives work well. They last a long time and have solid performance. Years of worry free service. Easy to install.

Perfect for any home server needs. Havent had any issues.

I bought two of these, one was Dead On Arrival. The first installed with no problem, I Installed the second one but got an error message that the disk was uninitialized and to first initialize it. First time I'd ever seen this error. Looked up the error information on the internet and it explained how to use the windows (Win 10 in my case) CONTROL PANEL -> ADMINISTRATIVE TOOLS -> COMPUTER MANAGEMENT -> DISK MANAGEMENT menu string to get to a screen that listed all my hard drives, including the new one which came up with the status of UNINITIALIZED and a message to click on the INITIALIZE option to fix it. As soon as I clicked on INITIALIZE I received another error message -> THIS REQUEST FAILED DUE TO A FATAL DEVICE HARDWARE ERROR. Searching the web for this error message basically indicated there was no way to recover from this and it should be returned to the manufacturer. The next day I took it back to Best Buy and they took it back as defective. They didn't have any more in stock at the store but they ordered a replacement one for me and it arrived at my house in two days. This one started up as expected and has been running fine now. My thanks to BestBuy for its return policy and help in getting a rapid replacement. The 3 rating was for getting a new, out of the box, defective hard drive, not BestBuys fault, BestBuy gets a 5 for the handling of the return process.

Western Digital has always been a leader in the HDD market. And lately since they have been branding their hard drives with "colors" it makes it a bit easier to choose according to your intended usage. Ours is used in a Unifi network with a Protect (Surveillance) module on the network. Our NVR has the purple drives specialized for surveillance.
